Explore our high-performance industrial valves and fittings, manufactured through state-of-the-art injection mold technology
Ehao Plastic Group is a high-tech private enterprise integrating the R&D and production of advanced building materials, industrial pipe fittings, and high-precision injection molds. As a recognized leader of PVC/UPVC ball valves in the domestic market in China, we have structured our engineering systems around scientific research, advanced metallurgy, and strict international standards.
Since our inception, we have partnered with prestigious institutions such as the Chinese Academy of Sciences and Zhejiang University in technological research. This academic backbone combined with our advanced German import computer-controlled automatic injection molding lines enables us to deliver unmatched repeatability, dimension stability, and surface finishes across all plastic injection products.
Every mold and component produced at our factories undergo a strict 26-step testing regimen. These comprehensive technical indexes fully accord with DIN8077 and DIN8078 standards, ensuring a 100% ex-factory pass rate and matching world-class operational lifetimes.
Our market coverage expands across Europe, North America, South America, and Southeast Asia. Ehao offers a full-suite manufacturing contract: from custom mold designs based on physical samples, pictures, or blueprints, to extrusion and injection mold processing. We design solutions for maximum wear resistance, cycle time reduction, and cost efficiency.
Global procurement teams in the automotive, medical, packaging, and fluid management sectors require more than just a steel tool. They require injection molds that optimize cycle times, reduce flashing, control warpage, and extend tool life. Sourcing from wholesale mold manufacturers in China involves analyzing complex variable metrics, including steel chemistry, runner systems (hot vs. cold runner technology), and cavity configurations.
Whether you require a prototype mold for limited-run validation or a multi-cavity Class 101 mold designed to run millions of cycles, establishing direct technical integration with the factory is vital. Ehao Plastic Group addresses these strategic demands by offering customized tooling design with integrated DFM (Design for Manufacturability) analysis, which minimizes engineering change orders (ECOs) late in the production timeline.
| Mold Class (SPI Standard) | Expected Cycles | Core/Cavity Steel Grade | Typical Applications |
|---|---|---|---|
| Class 101 (High Volume) | > 1,000,000H13, S136, 1.2344 (Hardened to 48-52 HRC) | High-precision automotive parts, thin-wall packaging, medical devices | |
| Class 102 (Medium-High) | 500,000 - 1,000,000 | P20, H13, NAK80 | Industrial pipe fittings, PVC ball valves, consumer appliance housings |
| Class 103 (Medium Volume) | 100,000 - 500,000 | P20, 718H | Custom domestic building products, garden bibcocks, decorative components |
| Class 104 (Low Volume) | < 100,000Alumec 89, Pre-hardened Steel | Prototyping, custom low-demand industrial adapters |
Ehao Plastic Group's tooling engineering services cater to multiple critical industries worldwide. By optimizing polymer flow behaviors, gas venting locations, and cooling line distribution, we deliver highly reliable plastic components for four distinct fields.
Our solutions for Home Decoration focus on cosmetic surface aesthetics, ensuring no visible weld lines or sink marks. For Irrigation Systems and Fish Cultivation, chemical compatibility and weatherization of PP, PVC, and UPVC compounds require thick-walled molding capabilities with specialized cooling channel structures. In Construction Work, our high-impact fittings and components adhere to structural load regulations and strict international plumbing standards.
The injection mold industry is undergoing a transition from traditional manual craftsmanship to automated, AI-assisted manufacturing systems. The integration of advanced computer simulation technologies ensures that the structural performance of the mold matches the expectations set by CAD models.
By leveraging metal 3D printing techniques, Ehao designs molds with conformal cooling channels that closely follow the contours of the mold cavity. This decreases cooling time by up to 35% and prevents deformation due to uneven cooling.
Utilizing Moldflow analysis allows our engineering team to predict air traps, fiber orientation, and shrinkage. This allows us to optimize gate locations before physical machining begins, cutting development timelines in half.
Modern high-volume manufacturing lines require predictive maintenance. Integrating pressure and temperature sensors inside the mold cavity enables real-time monitoring of polymer state changes, signaling maintenance teams before part failures occur.
With global legislation pushing for PCR (Post-Consumer Recycled) content, tooling must be engineered to handle wider viscosity ranges and contaminants. Our specialized gas-venting systems and abrasion-resistant coatings (like Chrome/PVD plating) ensure that recycled resins do not degrade tooling surfaces prematurely.
From selecting and configuring the right machine for your job to helping you finance the purchase that generates noticeable profits. Ehao is dedicated to enabling absolute efficiency across your production facilities.

Deploying injection tooling globally requires absolute compliance with local industrial standards and import regulations. Whether establishing tool parameters for North American manufacturing lines or shipping directly to European factories, structural and dimensional compliance is vital.
Ehao Plastic Group designs molds in accordance with DME and HASCO metric and imperial standards. This ensures that replacement parts, guides, and ejector pins can be sourced locally by our international clients. We align our structural designs with standard components to guarantee easy repair and minimal downtime.
Our Quality Management System is certified to ISO 9001:2015. Furthermore, our product lines match requirements set by international standard agencies:
Our logistical tracking systems ensure that tooling is shipped with complete steel certs, heat treatment documentation, and coordinate-measuring machine (CMM) inspection data, allowing for immediate integration into your manufacturing workflow upon arrival.
